Cascades Butterfly Project


Butterflies are sensitive indicators of changing environmental conditions because temperature influences the timing of an individual's life cycle and the geographic distribution of a species. The Cascade Butterfly Project has volunteers monitor the baseline butterfly habitat conditions to learn how climate is affecting their populations.



There are four sites in Washington state: North Cascades National Park, Mount Rainier National Park, Mount Baker-Snoqualmie National Forest, and the Okanagan-Wenatchee National Forest. The project is also active in two areas of British Columbia: Skagit and Manning Provincial Parks.

Cheers to butterflies

As the bartender drew pints of Silverspot India Pale Ale for the crush of people in the Pelican Pub and Brewery in Pacific City, Ore., recently, Michelle Dragoo, Siuslaw National Forest wildlife biologist, and Anne Walker, U.S. Fish and Wildlife Service biologist, prepared to tell the story of the butterfly that inspired the event. About 50 people grabbed a drink and a snack then settled in to listen.
